As quick breads go, carrot is popular and zucchini bread is even more so, which makes this one, with carrot and zucchini, an odds-on favorite. Many versions of zucchini cake contain walnuts, but not this one. It does have the requisite moistness of all well-made zucchini breads and a lovely spicy taste, though. If you are looking to gild this lily, spread a little cream cheese on each slice for a smart accompaniment to any tea tray in the late afternoon.
